1 Claim. 1
This invention relates to liquid level gauges, and more particularly to an improved automatic gauge for indicating the liquid level in underground storage tanks and the like.
A main object of the invention is to provide a novel and improved liquid level gauge which is simple in construction, which is easy to install, which provides accurate readings, and which involves only a few parts.
A further object of the invention is to provide an improved liquid level gauge which is inexpenslve to fabricate, which is easy to read, which requires a minimum amount of human supervision, and which is very durable in construction.
Further objects and advantages of the invention will become apparent from the following description and claim, and from the accompanying drawings, wherein:
Figure 1 is a side elevational view, partly in vertical cross-section, of a liquid tank provided with an improved level gauge device constructed in accordance with thepresent invention;
Figure 2 is an enlarged cross-sectional detail view taken on the line 2--2 of Figure 1;
Figure 3 is an enlarged cross-sectional detail view taken on the line 3'3 of Figure 1;
Figure 4 is an enlarged cross-sectional detail view taken on the line l---@ of Figure 1.
Referring to the drawings, H designates a 1iq uid tank, such as a tank adapted to be disposed with the top wall level with the ground and being adapted to receive a supply of liquid, such as gasoline or other liquid fuel. Adjacent one end thereof the tank l I is provided with a filler spout l2 through which the liquid may be poured into the tank. Rigidly secured to the top wall of the tank ll adjacent its other end is a vertical tube l3 communicating with the interior of the tank and provided at its top end with a vent fitting l 4 having the open elbow I5, directed downwardly as shown in Figure 1, providing free escape of air or other gas trapped in the tank H. Secured to the top of the fitting H5 is a transparent sleeve member I6, and journaled in the top end of the sleeve member-l6 is the transverse shaft I! on which is secured the drum or roller [8. It will be understood that the shaft Il may be rigidly secured rigidly to the shaft :7 and the shaft ll may be rotatable in the sleeve member I6.
Designated at I 9 is a flexible metal band, era
flexible band of other suitable material, which is disposed over the drum or roller [8 in the mam ner shown in Figures 1 and 2. The ends of the band I9 depend downwardly through the tube 13 into the tank H, and secured to one of the ends is a weight member 20. Secured to the other end of the band is a float 2!, and secured to said float is another weight member 22. Designated at 23 is a rectangular sleeve which is slidably engaged around the depending end portions of the band 19, the respective hand end portions being slidably retained between the opposite vertical end walls of the sleeve 23 and respective pairs of transverse pins 24, 24 secured in vertically spaced relationship in the front and rear walls of the sleeve 23, the respective pairs of vertically spaced pins as, 24 serving as spacer means between the depending portions of the band arranged to maintain said depending portions in spaced parallel relationship;
The outwardly facing surface of the band I9 is provided with appropriate calibrations, in the form of a scale of volumetric units, or alternatively, a scale of depth indications, indicating the level of liquid in the tank I I. The float 2| is. arranged to move upwardly and downwardly in response to changes in level of liquid in the tank, whereby the calibrations on the band 19 move around the roller 18' and come into view as the relative positions ofthe weights 20 and 22 shift due to changes in level of the liquid in the tank. It will be understood that when the level in the tank diminishes, the float 2! moves down along with the weight 22, whereas the weight 20 moves upwardly. The rectangular sleeve 23 engages either the float 2| or the weight 20, depending upon which of these elements is uppermost, in accordance with the level of liquid in the tank I I Threadedly engaged in the top end of the transparent sleeve 56 is the transparent dome or cap 25 which serves as a cover for the top end of tube l3, but which allows a clear view of the calibrations on the band l9, whereby the liquid level in tank ll may be read at all times.
While a specific embodiment of an improved liquid level device-for tanks has been disclosed in the foregoing description, it will be understood that various mo-difications within the spirit of the invention may occur to those skilled .in the art. Therefore, it is intended that no'limitations be placed on the invention except as do fined by the scope of the appended claim.
What is claimed is: v r q In a tank, a auge comprising a vertical tube secured to the top wall ofthe tank and communicating therewith, a roller 'journaled in the top end of said tube, a calibrated. flexible band 3 disposed over said roller, respective weights secured to the ends of said band, a float secured to one of said ends, said one of the ends depending into the tank and said float being arranged to move upwardly and downwardly in response to changes in level of liquid inthe tank, a sleeve member slidably engaged around the depending end portions of said band and supported on one of said weights, and spacer means secured in the sleeve member between said depending portions of said band and arranged to maintain said depending end portions in spaced parallel relationship.
